===========================CRITICAL HARD RULES (QWEN-SAFE)===========================

1. You MUST output the FULL ORIGINAL ARTICLE.
2. The ONLY allowed change is inserting ONE tag.
3. You MUST NOT add any comments, explanation, or any text outside the article.
4. You MUST NOT rewrite, reorder, delete, normalize, or alter ANY character.
5. You MUST NOT output the tag alone.
6. You MUST NOT place the tag at the beginning or at the end of the article.
7. The tag MUST be inserted inside a MIDDLE PARAGRAPH.

A “paragraph” = a block of text separated by one or more blank lines.A “middle paragraph” = any paragraph after the first paragraph and before the last paragraph.

If you break ANY rule → your output is INVALID.

===========================THE TAG (INSERT EXACTLY ONCE)===========================

Insert this exact structure:

Notes:• Replace MODEL_GENERATED_VALUE with the generated ticker.• Replace CATALOG_ID_VALUE with the matched catalog id.• Replace TIME_RANGE_VALUE with exactly one of: 0, 1, 2, 3, or 4.• DO NOT output any parentheses or explanations inside the tag.

The tag MUST be inserted at a natural boundary:• end of a sentence• or end of a line

Do NOT change any surrounding characters.

===========================HOW TO GENERATE THE ATTRIBUTES===========================

1. code (MODEL_GENERATED_VALUE)

Pick the single most relevant ticker found in the article.
If no ticker exists, choose the most relevant sector ETF based on context.If still unclear, default to SPY.

1.1 Crypto Rule

If the most relevant asset is a cryptocurrency:• Convert it to its USDT trading pair (e.g. BTC → BTCUSDT).• If the article uses the full name (e.g., “Bitcoin”), map it to the standard ticker first (Bitcoin → BTC → BTCUSDT).

This rule applies ONLY to crypto assets.Non-crypto tickers MUST stay unchanged.

2. id (CATALOG_ID_VALUE)

NEWS_BACKTEST may be:• a Python dict• a JSON string

Parse it if needed.

Choose ONE id from:data.newsBacktest[0].items[*].id

Selection MUST be based on semantic matching between:• ARTICLE text• items[*].details

If no strong match:• choose the item describing trend/momentum
If still unclear:• choose the FIRST item in the catalog

3. range (TIME_RANGE_VALUE)

Use a 5-year backtest window (timeRangeId="3") as the default.
Use shorter ranges (0–2) only for short-term contexts, and longer ones (4) for decade-scale structural themes.

===========================MANDATORY OUTPUT FORMAT===========================

You MUST output:✔ the original ✔ with the inserted tag inside a middle paragraph
✘ no explanation
✘ no extra text

ARTICLE:BitMine, a prominent Ethereum-focused treasury firm led by Tom Lee, added $150 million worth of Ether to its balance sheet this week, bringing its total holdings to over 3.73 million ETH. On-chain data from Arkham and Lookonchain confirmed the purchases, with transactions totaling $200 million over two days. The firm now holds more than 3% of Ethereum's circulating supply, inching closer to its stated target of 5% ownership.

The latest accumulation came via 41,946 ETH from FalconX and BitGo on December 5 and 22,676 ETH from BitGo on December 6 according to reports. At an average price of $3,028 per token, the purchases highlight BitMine's aggressive strategy amid a market downturn. This makes it the largest single corporate holder of Ethereum by volume.

In the final week of November, BitMine added 96,798 ETH, valued at $273 million, pushing its holdings to $8.95 billion. The company maintains $882 million in unencumbered cash for further acquisitions, a move that contrasts with a broader slowdown in corporate Ethereum treasury purchases. Industry data shows an 81% drop in monthly inflows since August.

Why the Standoff Happened

The aggressive accumulation by BitMine stands in stark contrast to the broader trend. Most major digital asset treasury companies have either paused or reduced their Ethereum purchases. For example, SharpLink Gaming and The Ether Machine have seen diminished activity since early 2025. November's inflows into Ethereum-focused treasuries were the lowest of the year, with net outflows recorded despite BitMine's continued buying.

BitMine's purchases occurred as the broader market struggled. Ethereum fell to a one-month low of $3,027, with smaller holders selling into weakness. Alphractal's Ethereum Accumulation Heatmap showed heavy distribution from wallets holding 1 to 10,000 ETH. This suggests a bearish near-term sentiment in the market.

How Markets Reacted

BitMine's accumulation strategy is part of a broader bullish thesis from its leadership. Fundstrat's Tom Lee has argued that Ethereum is entering a "supercycle," driven by network upgrades and potential Federal Reserve policy shifts. The Fulu-Osaka hard fork on December 3 enhanced scalability and data availability, aligning with the firm's investment rationale.

Despite the bearish market backdrop, BitMine continues to expand its footprint. It now holds more Ethereum than its next five peers combined, including SharpLink and the Ethereum Foundation. This dominance places BitMine second among corporate crypto holders, trailing only Michael Saylor's Strategy, which holds over 600,000 BTC (https://www.coindesk.com/business/2025/09/08/crypto-exchange-hashkey-plans-usd500m-digital-asset-treasury-fund).

What This Means for Investors

BitMine's treasury strategy has implications for both institutional and retail investors. The firm plans to launch its Made in America Validator Network in early 2026, transitioning from a passive holder to a yield-generating infrastructure platform. This initiative could generate several hundred million dollars annually in pre-tax income if it achieves a 3% staking yield on its current holdings.

The growing institutional interest in Ethereum is also evident in ETF-related demand. Strategic Ethereum Reserve data shows ETH held by staking entities and ETF-linked custodians rising from 3.5 million tokens in June to nearly 14 million by December. This indicates a shift from direct corporate treasury purchases to regulated investment vehicles.

As the year ends, BitMine's actions signal confidence in Ethereum's long-term potential. While the broader market remains volatile, the firm's continued accumulation highlights a structural shift in how institutions are approaching digital assets. For investors, this suggests a growing belief that Ethereum can serve as both a store of value and a core infrastructure asset in global financial markets.
